Affected Products and Versions

Remediation/Fixes

In order to fix this vulnerability, Java needs to be upgraded to 8.0.8.0 for TADDM versions 7.3.0.5 - 7.3.0.10.

Check java version installed on TADDM servers using the below command:

$COLLATION_HOME/external/<jdk- folder according to OS>/bin/java -version

• For TADDM 7.3.0.5 - 7.3.0.10 (JAVA 8), if the above command output contains**“SR6 FP10”**or “8.0.6.10” or higher as build in Java™ SE Runtime Environment information, apply e-fix for the new IBM SDK only,**efix_jdk8.0.7.20_FP10221123.zip **given in Table-1 below.

• For TADDM 7.3.0.0 - 7.3.0.4 (JAVA 7), Please upgrade to IBM Tivoli Application Dependency Discovery Manager Version 7.3.0.5 or later (Preferably to the latest release 7.3.0.10).

• For all other cases: Please contact IBM Support and open a case with TADDM version and a link to this bulletin.
